1 Claim.

The present invention relates to control oil or grease distributors andit consists in the combinations, constructions and arrangements of partsherein described and claimed.

It is an object of the present invention to provide a control oil orgrease distributor by which a machine such as, for example, a combineharvester may be lubricated from a central; location. I

Another object of the invention is the provision of an apparatus of thecharacter set forth which is adapted to successively distributelubricant under pressure to a plurality of oil or grease lines.

Another object of the invention is the provision of novel means andmechanism whereby lubricant under pressure may be distributed from asingle source to selected lubricant receiving lines.

Another object of the invention is to provide an apparatus of thecharacter set forth which is simple in construction and operation andwhich is eiiective and efiicient in use.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawings, in which:

Figure 1 is a side elevational view of an embodiment of the invention,

Figure 2 is an enlarged vertical sectional view thereof,

Figure 3 is an end view of Figure 2,

Figure 4 is a view similar to Figure 2 but showing certain parts inelevation,

Figure 5 is a sectional view taken along line 5-5 of Figure 4, and

Figures 6 and 7 are perspective views of certain elements of theinvention.

Generally, the invention comprises a distributor for lubricantconsisting of a substantially cone-shaped outer member into the smallerend of which is tapped a line which is, in turn, connected with a greasegun or like source of lubricant under pressure. A conical inner memberis provided with a groove extending longitudinally in its outer sidefrom the smaller end thereof to a point adjacent the larger end thereof.Means is also provided for locking the inner member in adjusted axialrelation within the outer member and a plurality of fittings are placedin the outer member in such manner as to register one at a time with thegroove whereby lubricant is fed under pressure to selected fittingswhich are interconnected by pipes or the like to the parts to belubricated.

Referring more particularly to the drawings, there is shown therein acontrol distributor for means of brackets l2.

In a flattened smaller end l3 of the member ID is-a fitting M. A greasegun 15 or the like is connected to the fitting M by means of a pipeWithir'r the outerconical member 10 there is provided .a closely fittinginner conical member ll which-is provided with a longitudinal slot [8which extends from its flattened smaller end I9 to a point adjacent thelarger end thereof.

A plurality of fittings 20 are positioned in the outer member ID in suchmanner that but one thereof may register with the groove [8 regardlessof the position of the inner member I! with respect to the outer memberIn. To each of the fittings 20 is connected a pipe line 2| whichinterconnects in each case with a part of a machine to be lubricated.

Affixed to the rear or larger edge of the member III, by means of screws22 or the like, is a transversely extending bracket 23. The larger orrear edge of the inner member I1 is provided with a series of notches28.

A centrally disposed tension bolt 29 extends through an enlarged portion30 of the bracket 23 and is threaded therein and a bearing 3! isthreaded upon the outer end of the bolt 29. The tension bolt 29 isprovided with an oper-- ating handle 34 upon its outer end and with anintegral collar 32 adjacent its inner end.

Pivotally mounted upon the bearing 3| is a lever 40 having an operatinglink 4| connected to its outer end and is provided with a pawl 42 whichis in engagement with the teeth 28. A pair of stop pins 43 and 44 areailixed to the outer edge of the member [0 and limit the movement ineither direction of the lever 40. Afiixed to the bracket 23 is a detent45 which is in the path of travel of a final stop pin 46 carried by themember ll.

In operation, it will be understood that oil or other lubricant 34 isfed by means of the gun I5 or like apparatus through the pipe l6 intothe outer member I0 and thence through the groove l8 through thatparticular fitting 20 which is then in registry therewith and thencethrough the pipe 2| connected with such fitting to the part to belubricated. The operator, having lubricated one machine part in themanner now described may then reciprocate the link 4| either manually orby automatic mechanisms not shown and each such movement will cause themember I] to revolve a distance of one of the teeth 28 to bring the nextopening 20 into alignment with the groove 18. When the stop member 46 isencountered by the detent 45, all of the openings 20 will have come intoregistry with the groove [8 and the lubrication will have beencompleted. The pins 43 and 44 are so placed as to limit the movement ofthe lever and its attached pawl 42 in such manner that only one tooth 28is engaged and moved through one reciprocation of the lever. Themovement of the link 4| may be timed, if so desired.

While but one form of the invention has shown and described herein, itwill be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed is:

An apparatus of the character described comprising an outer conicallyshaped member, an inlet pipe at the smaller end of said outer member, aplurality of outlet pipes connected to the outer member in spaced axialrelation, a conically shaped inner member revolubly mounted in closealignment within said outer member and having a groove extendinglongitudinally in the outer side thereof from the smaller end thereof toa point adjacent the larger'end there- 4 of and having a series of teethformed in its larger end, adjustable tensioning means for holding theinner member in engagement with the outer member, said means comprisinga bracket mounted on the outer member and extending transversely acrossits larger end and a bolt threaded in said bracket and bearing againstsaid inner member, and a handle revoiubly' mountedon the bracket andhaving a pawl ailixed thereto for selective engagement with said teeth.
